Comments
26 signed letters in a cursive script to Dionigi Guerrini, quartermaster-general of Ferdinand II de' Medici, Grand Duke of Tuscany, in which Borelli discusses the progress of his works Lettera del movimenti della cometa apparsa il mese di dicembre del 1664 (1665), Theoricae mediceorum planetarum (1666), and De vi percussionis (1667). He also mentions the astronomer Galileo Galilei and the astronomer-physicist Evangelista Torricelli. 21 letters are written on bifolia, with the remaining 5 written on single leaves, with a variety of watermarks. 18 of the letters are written from Pisa (letters 1-12, 17 November 1664-2 April 1666; letters 19-24, 22 December 1666-27 May 1667), 6 are written from Poggio Adorno or Villa (letters 13-18, 28 November-19 December 1666), the latest letter is written from Naples (letter 26, 21 June 1667), and one letter has no date or place of writing (letter 25). Some of the letters have remnants of seals and are addressed to Guerrini in Florence or Poggio Adorno.
